Now that we’d addressed the tire rubbing out back, we wanted to gain back some of the compression travel we’d eliminated. The easiest way to accomplish that was to add a pair of Currie XJ shackles. Made by JKS Manufacturing, the Currie shackles are 5 inches long in contrast to the 3-inch stock shackle. Since the leaf springs’ locating pin sits toward the front of the spring instead of in the middle, the extra shackle length adds about 3/4 inches of ride height.
